A major challenge for spin-based information technologies is the generation of spin polarization in otherwise nonmagnetic materials. Here, Arnoldi et al. demonstrate how ultrafast laser excitations can be used to generate spin polarization in a fullerene/tungsten diselenide heterostructure.
Bergenin is a rare C-glycoside of 4-O-methyl gallic acid with multiple pharmacological properties. Here, the authors report the elucidation of the biosynthetic pathway of bergenin in Ardisia japonica and its bioproduction by engineered E. coli.
The factors that determine the direction of traveling waves in the brain are not well understood. Here, the authors show that the sum of incoming structural connection strengths shape both traveling wave direction and frequency gradients.
Even though glucocorticoids are potent anti-inflammatory agents, they can cause muscle wasting. Here, the authors show that targeting the glucocorticoid receptor coactivator LSD1 limits muscle loss without reducing the drugs’ efficiency on the immune system.
The electronic correlation-driven Mott metal-insulator transition has been predicted in a 2D metal-organic framework with a kagome structure. Here the authors synthesize such a system in experiment and demonstrate an electrostatically controlled Mott transition.
The regulatory mechanism and functional consequence of lysine lactylation remain to be explored. Here, the authors identify HBO1 as a lysine lactyltransferase and suggest a potential role of HBO1 in tumorigenesis through H3K9la-mediated transcription regulation.
Tuning the physical interactions and structures to govern the viscoelastic properties in hydrogels without altering the chemistry is challenging. Here the authors design a complexation gel composite and utilize the physical principle of topologically frustrated dynamical state to tune the correlated structures between the guest polycation chains and negatively charged host gels.
Here, the authors perform large trans-ancestry fine-mapping analyses identifying large numbers of association signals and putative target genes for colorectal cancer risk, advancing our understanding of the genetic and biological basis of this cancer.
Triacylglycerol remodeling in Physaria fendleri changes the seed oil fatty acid composition after initial synthesis to overcome metabolic bottlenecks in the accumulation of valuable unusual fatty acids. This process enhances designer oil engineering.
A regulated stress response is essential for healthy child growth and development. Here, the authors show that a nutrition, water, sanitation, and hygiene intervention enhanced adaptive responses of the physiological stress system in early childhood.
Rare disease DEDSSH1-associated DPH1 mutations impair eEF2 diphthamide modification that leads to eEF2 as a transcriptional coactivator for p53 to enhance expression of the cell proliferation inhibitor p21, resulting in birth defects.
Confining atoms to lattices can modify their interaction and collision. Here the authors show suppression of dipolar relaxation in the form of reduced decay rate of dysprosium atoms in quasi-2D regime.
Oxygen is an essential requirement for aerobic organisms. Here the authors explore the role of oxygen in the antiviral innate response in multiple models of infection and suggest oxygen enhances the antiviral innate response via EGLN1 hydroxylation of IRF3.
The surface charge and ζ-potential of biomolecular condensates is key to their interactions with membranes and proteins. Here, the authors developed a method to determine the ζ-potential of condensates using microelectrophoresis and single-droplet tracking.
The pore-forming toxin pneumolysin is responsible for the high mortality seen in pneumococcal infections unresponsive to antibiotics. In this work, authors report a small molecule inhibitor targeting pneumolysin and related ones as an anti-virulence strategy protecting human cells during infection.
When the Marinoan snowball Earth deglaciated, the ocean’s chemistry determined the strength and duration of the ensuing supergreenhouse climate, while the sudden warming and biological activity could have led to a rapid formation of cap dolostones.
The authors demonstrate 3D chemical imaging of organic and inorganic materials near or below one-nanometer resolution using multi-modal electron tomography, by fusing elastic and inelastic scattering signals.
The human papillomavirus (HPV) E6 oncoprotein hijacks the ligase activity of the host E6AP to ubiquitinate the tumor suppressor p53. Here, the authors show how the presence of the HPV E6 oncoprotein transforms the inactive E6AP monomer into an active dimer, providing a structural understanding of the physiological and pathophysiological mechanisms of E6AP function.
Manipulating the electronic properties of topological semimetals is a central goal of modern condensed matter physics research. Here, the authors demonstrate how a high-entropy engineering approach allows for the tuning of the crystal structure and the electronic states in a Dirac semimetal.
Point defects in 2D semiconductors have potential for quantum computing applications, but their controlled design and synthesis remains challenging. Here, the authors identify and fabricate a promising quantum defect in 2D WS2 via high-throughput computational screening and scanning tunnelling microscopy.
